Ferrite Cable Cores

What are Ferrite Cores?

In the transmission system, noise is classified in two ways: one is differential mode noise and the other is common mode noise. A common mode signal (noise) is an unwanted signal as it “carries” no information. A ferrite cable core is designed to clean common mode noise (signal) generated from either a signal line or power cable.

How do Ferrite Cores Work?

Ferrite cores are used to suppress electromagnetic emissions by blocking low-frequency noise and absorbing high-frequency noise. This avoids electromagnetic interference.

How to Choose the Right Ferrite Cable Core

Firstly, confirm the “problem frequency” and then the available space. The next step is to select an appropriate ferrite core (refer ID , OD and length of this ferrite core) with as higher an impedance as possible which can cover the problem frequency.

Benefits of Laird Performance Materials’ Ferrite Cores

Why Steward and Laird? Our companies have combined to set performance standards worldwide. Laird Steward follows in the footsteps of Steward, well known by the biggest and brightest technology teams designing, manufacturing and delivering high quality, high performance EMI protection solutions.
